The rev counter uses the connection marked 'w' on the alternator, check this wire?
The light staying on is possibly a diode in the alternator, have been told there are 9 in total.
Mine now runs a 93 Fiesta diesel alt. You have to part strip it and turn the mounting brackets and swap the pulley, but it was free from a neighbor breaking his van  :lol: but you can pick one up from the scrappers for £10-£15. cheap fix if you got the time and a few tools

I've got a 65 amp 'spare', they fetch around £35.

I have a 100 amp that needs the mounting lug re-attaching so you could have that for the same.  Your big problem is running a big alternator from the standard Vee belt, an 80 amp is a trial for it.  I fit a 675x13mm belt rather than 675x10, fortunately Halfrauds stock the thicker belt in just the right size.

If you ever see one the 80 amp does go on, I run an alternative belt that's wider to cure the belt burning problem and I have the stronger belt tensioner (screw thread type) on the alternator, it runs ok.  One of the big probs with the V8 is that the alternator bracket bends over time, especially when some numpty doesn't refit the brace bar.  Eventually the belt is running slewed on the pulleys and wears rapidly.  I could get though one in an afternoon until I fixed it.


The 100 amp unit had a flat multi Vee belt, this requires a different crank pulley to suite and PAS pulley with a guide pulley on the front, as on '93 SE/LSE.

Replaced 65a it did have a 80a on it but where I got it from just sent me the 65a one.
It works and runs the car seems much better now  :) so it will have to do.
